A non-sterile implantable device designed to replace or repair (fuse) the spinal bony segments, or vertebrae, lost or injured as a consequence of, e.g., trauma, deformity, tumour, or degenerative disease. It is typically intended to be used with supplemental spinal fixation and may be used with a bone graft. It is usually made of metal, polymer, or a combination of these materials. This device must be sterilized prior to use.
